The next generation of microprocessors may have to be cooled to –100 °C. IBM has experimental chips running at speeds between 2 and 3 gigahertz, which need to be cooled to maintain “switch-off” times for their supersmall 0.1-micrometre-wide transistors, according to Yuan Taur of IBM in New York. IBM will announce the details at the International Electron Devices Meeting in Washington DC next week. Low temperatures overcome the leakage problems that cause the poor switch-off performance. Such cooling is impractical in laptops,
